DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a W / O type makeup cosmetic comprising water-repellent powder and water, and more particularly to water-repellent powder. Has a structure in which water droplets are finely dispersed between powders, and has excellent use characteristics (spread, adhesion, refreshing feeling, keeping makeup), and is suitable as a W / O type makeup for summer foundation. Related to cosmetics.

[0002]

BACKGROUND OF THE INVENTION Make-up cosmetics using water include water, surfactants,
2. Description of the Related Art Cream-type foundations prepared by dispersing a powder in a milky lotion or cream composed of an oil agent or the like are conventionally known. These foundations have characteristics of good spreadability and stickiness, but they have problems in keeping makeup, and because they contain surfactants, they have the problem that they can easily collapse under harsh conditions such as sweating and swimming in summer. Was.

[0003] In addition, the cake-type foundation is currently the mainstream because it has excellent properties such as keeping makeup, water resistance and ultraviolet protection, but it is more difficult to apply at the time of application than a cream-type foundation. There was a lack of smoothness.

[0004] On the other hand, there is an oil-based foundation which has excellent properties such as preserving makeup, water resistance and UV protection, and has a smooth feel upon application. However, since the amount of the oil agent is large, it has a refreshing feel. There was a problem that could not be obtained.

[0005] In view of these problems, the present inventor has excellent performance in keeping makeup, water resistance, UV protection, etc., has a smooth feel upon application, and has a refreshing refreshing finish. As a result of earnest research on makeup cosmetics that can be obtained, water is mixed and dispersed in water-repellent treated powder to obtain a structure in which water droplets are finely dispersed between powders. It has been found that when applied to the skin, it has a cool and refreshing feel because it acts as a cooling agent.

That is, an object of the present invention is to mix and disperse water in a water-repellent treated powder, thereby obtaining a structure in which water droplets are finely dispersed between the powders, excellent in use characteristics, and a cool and refreshing feel. The present invention provides a W / O type makeup cosmetic that can be used.

[0007]

The degree of water repellency of the powder used in the present invention is required to be 25 to 100 when the method for measuring water repellency described in Examples described later is used. , Preferably 30 to 100. That is, the water repellency is 25
In the case of less than for the water repellency of the powder is insufficient, in the case of the products of the present invention has been created, manufactured by deterioration of feeling, collapse makeup by sweat, because problems such as corner Irogu occurs.

When the water repellency of the following treated powder was measured using this method for measuring water repellency, the water repellency was less than 25. Further, when the product of the present invention was prepared, Separation, deterioration of the touch, etc. occurred. Metal soap treated powder 1. Powdered metal salt of myristate 2.

In the present invention, it is preferable not to use a surfactant such as an anionic surfactant, a cationic surfactant and an amphoteric surfactant. When these surfactants are used, the water-repellent treated powder is wetted by the action of the surfactant, so that the water resistance is reduced, and the refreshing feeling of the present invention cannot be obtained. Therefore , even when a surfactant is used for the purpose of touch preparation, the amount of the surfactant
As it is, 0.1% by weight or less with respect to the cosmetic 100% by weight
It needs to be below .

In the present invention, ethanol, methanol and isopropyl alcohol can be blended as components other than the water-repellent powder, oil agent, silicone oil and water. However, since these lower alcohols lower the water repellency of the water-repellent treated powder similarly to the surfactant, the lower alcohol is used in an amount of 0.1% by weight of water in the cosmetic.
It is preferably from 20 to 20% by weight, more preferably from 0.1 to 5% by weight.

When a water-repellent treated powder treated with a fluorine compound is used, the mixture of the above-mentioned fluorine-modified silicone and dimethylpolysiloxane is effective as an oil agent to be blended. In other words, the water-repellent treated powder treated with the fluorine compound has a strong water repellency and repels oils such as higher fatty acids, higher alcohols, and ester oils, so that the treated extender under severe conditions such as swimming. May run off. On the other hand, the mixture of the fluorine-modified silicone and dimethylpolysiloxane has an effect of fixing the water-repellent powder treated with the fluorine compound on the skin and further reducing the degree to which the oil agent is repelled.

In this case, the structure of the fluorine-modified silicone is represented by the following general formula:

Embedded image As shown in the above, it is preferable to include a dimethylsiloxane unit. In this equation, the value of a, b, and n is such that a is 2
-12, b is preferably 4-12, n is preferably 1-8, and n is more preferably 1-3. When the fluorine content is large, the fluorine-modified silicone phase-separates with dimethylpolysiloxane and an oil agent, which causes problems such as stability over time and color change after application to the skin.

A method in which the water-repellent treated powder, the oil agent, and the silicone oil are stirred and mixed using a Henschel mixer or the like using a mixing device, and then water is added to further stir and mix. 3. After coating the water-repellent treated powder with an oil agent and silicone oil using a blast air dryer, spray dryer, etc.,
A method in which the obtained powder is stirred and mixed with water using a stirring and mixing device such as a Henschel mixer. 4. A method in which a water-repellent powder, an oil agent, silicone oil, and water are charged into an apparatus such as a ball mill, an ong mill, a vibration mill, and a roll mill, and are stirred and mixed. 5.
